CIRCUIT NOISES

NOT ALWAYS STATIC. PROBLEM OF BATTERIES. Every set owner naturally begins to |nok for static disturbances with the advent of warm weather, but when the familiar crackle is ushered in with the first approach of winter the only deduction he can draw is that atmospheric disturbances are not purely a function of heat and moisture after •11. On the following morning he asks his nearest radio neighbour whether or not be was troubled with static on the previous evening. This fan who has just purchased a new battery vigorously denies that he had any trouble, and describes several new stations heard by him as “clear as a bell.** Strange thing this static business, particularly when two men live within a 50 yard radius and use exactly the same type of radio receivers. There follows a few nights more of the same sort of grief, and then our party of the first part buckles down to a serious investigation of the problem. On testing his B battery simply as a matter of routine he discovers that it is way down and buys a new one. Further, he charges his A battery _to the standard full charge mark of 12.75, and when all of these operations have been completed he tunes in again. Gone is the static, the scratching, the crashes, the rattles and the grating that was formerly assumed to be static.
